BIG-IP CGNAT - v15 - PBA periodic block refresh logs

Hellos Devs!

 

I read on v15.0.0 release notes that you could now send periodic block refresh logs.

 

https://techdocs.f5.com/kb/en-us/products/big-ip_ltm/releasenotes/product/relnote-bigip-15-0-0.html

"CGNAT: Port Block Allocation periodic block refresh logs

This release includes a new logging option that logs Port Block Allocation (PBA) block periodically with a configurable refresh time"

 

I tryed to find this option on the GUI and CLI but I just can't find it. Even tryed on v15.1.0.

 

Does anybody knows where it is hidden?

 

Thanks, Rafael

    if you are using the CGNAT instead of AFM security you will find it under "Carrier Grade NAT ›› Policies : Source Translation"

    I was not finding this option because I believe it's only available on the "new method", with a policy. If you enable "Legacy LSN Pools Editor" you don't see this option on the GUI or CLI.

    Hi Rafael,

     

    I don't know that if any new documents aside from the one already published will be available. If it can help I know you can find that setting in this document

    Thanks Stefano! I will check those options soon! Is there a plan to release a configuration guide for the new way of CGNATing on the GUI? I saw that the GUI is different from v13 and v14. Just trying to wrap my head around it...

    Hello Rafael,

     

    I believe you can find the setting under the TMUI "Security → Network Address Translation (NAT) → Source Translation" on the object you have or need to create. If you select type: Dynamic-PAT and PAT mode: Port Block Allocation you should be able to see "Periodic Refresh Log :" setting, which is in minutes. If you prefer TMSH you have it under

     

    root@(vbigip-tier2)(cfg-sync Standalone)(Active)(/Common)(tmos)# create security nat source-translation srcTranslation1 pat-mode pba port-block-allocation { per?

    Properties:

     periodic-refresh-log  

    root@(vbigip-tier2)(cfg-sync Standalone)(Active)(/Common)(tmos)# create security nat source-translation srcTranslation1 pat-mode pba port-block-allocation { per

     

    Thanks

    Stefano
